If you want to detect something like stackoverflow.com, then you're going to have to check for all possible TLDs to rule out something like Web 2.0, which is quite a long list. Still, this is also going to match something as ASP.NET etc.

The regex would looks something like this:

$hypertext = preg_replace(
    '{\b(?:http://)?(www\.)?([^\s]+)(\.com|\.org|\.net)\b}mi',
    '$1$2$3',
    $text
);

This only matches domains ending in .com, .org and .net... as previously stated, you would have to extend this list to match all TLDs
